SUPPORT FOR SPINNlNG-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 408,264, dated August6, 1889.

Application filed March 15, 1887. Serial No. 231,047. (No model.)

To all whom it may concern:

Beit known that I, FRANCIS SEYMOUR, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Support for Spinning-Spindles, of whichthe following is a specification.

This invention relates to improvements in spinning-spindles; and the object of my in- Io vention is to provide a new and improvedspinning-spindle which can be run at an exceedingly high speed withoutheating or expanding unduly.

A further object'of my invention is to simplify the construction of themounting for the spindle.

The invention consistsin the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, 2o andpointed out in the claims.

Inthe accompanyingdrawing my improved spinning-spindle is shown with itsmounting, the spindle, its retainer, and supporting device being inelevation and other parts being in section.

The spindle a, which upon its upper part may carry or support either a ysupply or receiving spool of the well-known construction, is providedwith the whirl 71 around which a cord for driving the spindle is to bepassed. On the lower end of said spindle a a pintle is formed, whichrests in a suitable step formed in the revoluble bearing b. Said bearinghas a whirl i, around which a cord is to be passed. for revolving it,and consists, essentially, of a hollow stem closed at the lower end andopen at the top and cylindrical and smooth on its outside. Said bearingb is guided or retained in a frame c, having an upwardly-projecting partc4, which is passed loosely into an aperture d3 in the rail or supportd, the lower part of the frame cbeing enlarged to receive the whirl e'.The bottom part of said frame c rests upon a should er 7o, formed on thetop flange or head of a footpiece c2, having a step in which a pintle onthe lower end of the revoluble bearing b runs. The foot-piece c2 isprovided inl its lower end with a groove or notch g, into which theupper portion of a substantially elliptical loop fm passes. Said loop isformed of a wire f, which is U-shaped, its ends being bent to fornihooks that engage ribs on the upper surface or the rail d along the sideedges, whereby the frame c, the 'foot-piece c2, the rev- 55 olublebearing l and the spindle a .arc suspended by means of said wire f fromthe rail d, and the frame c and foot-piece c2 are held together withoutthe use of screws or like devices, and the entire construction of themounting is simpliiied. The entire de vice can give more or less withthe point n as the fulcrum, and my improved spinningspindle is thusyielding and can give, heilig brought back into the normal position bythe spring-wire f. This is very essential in highspeed spindles, asrigid mountings are very apt to produce an undue friction. The spindle ais prevented from being pulled out of its bearings when the spool isremoved by the rctainer on the rail CZ.

The difference in the size of the whirls 7L and can be varied accordingto the requirements. The whirl h, being the smallest, turns faster thanwhirl e'.

If, for example, the whirl 7L is onlyhalf the size of whirl c', theresult will be that while the bearing l; is making one turn the spindlea, though making two turns, makes only one in its bearing, thuspermitting of attaining exceedingly high speed without causing heating,undue expansion, or undue wearing of the parts.

The bearing h and spindle CL are rotated independently, inasmuch asseparate and independent devices are used for driving each.

I do not claim'in this application the rotating or live spindle and atube containing bolster and step bearings for the spindle and providedwith a whirl, whereby the said tube may be rotated, in combination witha case or holder for the tube and a step for'the tube, broadly, or thespindle, the bearing-tube provided with a whirl, and a step for thetube, combined with means to rotate the said spindle and bearing-tube,broadly, the same not being my invention.

Having described my invention, whatI claim as new, and desire to secureby Letters Patent, 1s

l. The combination, with a spindle having a pintle, of a revolublebearing provided IOO with a step for receiving` and supporting thepintle of the spindle, a support for said revoluble bearing, and aspring for suspending said support from a rail or holder, substan- 5tiallyas herein shown and described.

2. The combination, with a rail or holder, of a frame under said rail, afoot-piece below 'said frame and supporting the same, and L spring'supporting jche foot-piece, said spring Io being held 011 the rail orholder, substantially as herein shown and described.

3. The combination, with a rail or holder,

of a f1a-me-piece below it, L foot-piece supporting the frame, L spring'supporting' the foot-piece and held on the rail, a revoluble 15 bea-ringin the frame and foot-piece, and a spindle having a pintle which restsupon a step in the revoluble bearing, substantially as herein shown anddescribed.

FRANCIS SEYMOUR.
